Q&A – Why did my pecans dry up on the inside of the shell?

Question:Why did my pecans dry up on the inside of the shell?

Answer: There are several reasons this could happen. One possible reason is pecan scab. Scab was common this year because conditions were favorable. The scab interferes with photosynthesis which reduces the tree’s ability to use the energy from photosynthesis to grow pecans. It could also be a lack of nutrients. Pecan trees need a lot of fertilizer to grow a large crop. They need so much that you can not put enough down on your lawn under the tree without burning up the lawn. If your tree was loaded with pecans the tree may not have been able to get enough nutrients to grow all of them.
